IMsCointegrationEquationTransform.Result

Syntax

Result: IMsFormulaTerm;

Description

The Result property returns the term corresponding to output variable.

Comments

To get exogenous variables, use the IMsCointegrationEquationTransform.Operands property.

Example

Executing the example requires that the repository contains a modeling container with the MS identifier containing an error correction model with the MODEL_COINTEGRATIONEQ identifier.

Add links to the Metabase, Ms, Stat system assemblies.

    arr := Eq.Result.Serie(Calc);
    For i := 0 To arr.Length - 1 Do
        Debug.WriteLine(arr[i]);
    End For;
    (Model As IMetabaseObject).Save;
End Sub UserProc;

After executing the example the model parameters are changed, all exogenous variables are included into the group describing short-term cointegration relations, output variable data is displayed in the console window.
